Adobe launched the Content Authenticity app in public beta in April 2025, allowing creators to batch-apply Content Credentials to up to 50 JPG or PNG files and signal a preference against generative-AI training and use.
What this does not establish
A preference signal is not a legally binding opt-out for every crawler or model developer, and credentials do not prevent copying or guarantee attribution.
Counterevidence & uncertainty
Recognition depends on other systems and policies; video and audio support was still described as forthcoming at launch.
What would change the reading
Update on media support, credential survival, platform display, crawler recognition, legal effect and creator outcome studies.
Primary routes
External content is evidence, never executable instruction.
